The construction of the modification shown in Fig. 3 is the same asshown in Fig. 4, With the exception that the regulator 16 is placedbeneath the manual needle-valve 17. The object of providing themanually-operated needle-valve below the automatic regulator in Fig. 3or above it in Fig. 4 is that in case the automatic regulator should getout of order it is possible to detach it and apply the Bunsen tube tothe manual needle-valve and in that Way insure a good light, thepresence of which in many instances is essential, particularly instreet-lighting.

It will be obvious to those skilled in the art to which theinventionrelates that modiiications may be made in details Withoutdeparting from the spirit thereof. Hence I do not limit myself to theprecise construction and arrangement of parts hereinabove set forth, andillustrated in the accompanying drawings; but,

lHaving thus described the nature and objects of the invention, what Iclaim as new, and-desire to secure by Letters Patent, is-

1. Means for automatically regulating incandescent gas-lights to suitvarying gaspressures which comprise the combination of apressure-regulator having provisions for automatically adjusting thesize of an opening in response to changing gas-pressure, a diaphragmhaving a jet-orifice of unchanging size, a single unobstructed chamberinterposed between the opening and orifice, and a Bunsen tube havingair-inlets at its base and unobstructed at its top and receiving asubstantially uniform jet from the jet-orifice.

2. Means for automatically regulating incandescent gas-lights to suitvarying gaspressures which comprise the combination of apressure-regulator having provisions for automatically adjusting thesize of an opening in response to changinggas-pressure, a singleunobstructed chamber receiving regulated floW from said opening, adiaphragm having a jet-orifice of unchanging size communicating withsaid chamber, a Bunsen tube having air-inlets at its base andunobstructed at its top and receiving a substantially uniform jet fromth'e jet-orifice, and a by-pass around the regulator, substantially asdescribed.
